My lab is interested in how the gut microbiota use the complex glycans available to them within the human gut, focussing on the Bacteroidetes. We are particularly interested in glycoside hydrolase enzymes that target the glycans of pathogens such as Mycobacterium tuberculosis and Candida albicans. Finding these enzymes in gut bacteria allows us to uncover new enzymes in the pathogens themselves. We use a combination of microbiology, biochemistry, glycobiology and structural biology to understand the activity and function of these enzymes. We are also interested in the mechanisms of how Bacteroides sense and respond to the glycans they encounter using unusual hybrid two-component systems, and how they use the Type 9 Secretion System to enable extracellular glycan degradation.
